On page 7966, S. F. Zhou and co‐workers report a vital and unprecedented link between the structural constraints of disordered glass and the chemical state of dopants, and propose a milestone approach to modulate the chemical state of the dopants over a wide range of length scales by engineering the topological features of the host glass. Not only does this pioneering approach substantially upgrade the optical performance of a doped material, but it also constitutes a giant step toward the fundamental insight into the origin of the “concentration quenching” phenomenon in luminescent materials.
